JAMES C. DORAN AND JAMES A. DORAN, OF PAVVIUOKET, RHODE ISLAND.

JEWELRY COMPONENT.

SPECIFICATION forming part of Letters Patent No. 767,687, dated August16, 1904.

Application filed May 3, 1904. Serial No. 206,108. (No model.)

To all whom it may concern:

Be it known that we, JAMES C. DORAN and JAMES A. DORAN,'bO'th citizensof the United States, residing at Pawtucket, in the county of Providenceand State of Rhode Island, have invented a certain new and usefulImprovement in Jewelry Components, of which the following is aspecification, reference being had therein to the accompanying drawings.

Our invention relates to that class of jewelry components which areapplicable to and form a part of brooches, breastpins, and similararticles.

It is the universal custom of jewelers to purchase their pin tongues andjoints and apply the same to whatever ornamental body they desire. Aminimum of pieces to be applied, therefore, is a desideratum because ofthe time arid expense saved thereby. Furthermore, the use of structuresinvolving pintles and 1 their equivalents besides increasing expense ofmanufacture are unsatisfactory because of the weakness of the partsoccasioned by the bearing-perforations.

To the end of obviating the above defects and attaining the enumeratedadvantages, our invention consists in the novel construction andcombination of parts hereinafter described, and illustrated in theaccompanying drawings, Wherein Figure 1 is a perspective view of our newcomponent; Fig. 2, a central longitudinal section of the same applied toa base or body; Fig. 3, a perspective view of the tubular foundation ofthe catch; Fig. 4C, a central longitudinal section of the same; Fig. 5,a perspective of the same after the flattening operation; Fig. 6, acentral longitudinal section of the same; Fig. 7, an end elevation ofthe completed catch, and Fig. 8 a perspective of a modified form ofcatch.

Similar reference-letters indicate like parts throughout the views.

Our improved component comprises a back plate A, of sheet metal,provided with an integral hemispherical recess B, having uprightparallel side walls 6 and an oblong segmental opening or slot 6intermediate the walls.

The catch is formed by punching a tubular projection C in the plate A,as shown in Figs. 3 and 4. This projection is then flattened to the formshown in Figs. 5 and 6. The flattened tube is next transversely cut bysuitable dies into a hook form 0, which completes the catch member.

A modified form of our catch is shown in Fig. 8, which is formed fromthe tubular projection C and is flattened somewhat by suitable dies,having a portion of one of its narrowest sides removed and provided alsowith an adjacent horizontal opening to allow ingress of the pin-tonguepoint.

Mounted in the housing B and contacting with the side walls thereof isthe head (Z of the pin-tongue D. While the head is illustrated hereinwith a transverse opening, the latter is not necessary, as animpcrforate head may be used, it being only essential that the head benot spherical and provided the head be not smaller than the slot 6'.

Our component is utilized by fixing the plate A in any suitable mannerto the ornamental body or face-plate E, which forms a bearing for thelower portion of the head (Z.

It will be further noted concerning our invention that the existence ofthe slot 6 in the forward upper portion of the housing B affords abearing not only for the downward travel of the pin-tongue D, but also,as regards its interior margin, for the head of the pin-tongue (Z.

Having described our invention, what we claim is 1. In a device of thecharacter described, the combination with a face-plate of a back platefixed thereto and having integral therewith a hemispherical recess withflattened sides, and having a segmental slot.

2. In a device of the character described, the combination with aface-plate of a back plate fixed thereto and having integral therewith ahemispherical recess with flattened sides, and having a segmental slotand a pintongue provided with a flat circular head mounted in the recessand bearing upon the flattened sides thereof and supported therein bythe face-plate.

3. In a device of the character described, In testimony whereof We haveafiixed our the combination with a face-plate of a back signatures inpresence of two Witnesses. plate fixed thereto and having integralthere- JAMES C DURAN c With a hemispherical recess with flattened JAMESDORAN' A sides and having a segmental slot, and a pintongue providedwith a flat circular head Witnesses: mounted in the recess and bearingupon the HORATIO E.
